Edward had scarcely recovered from his defeat and disgrace at the hands of the Scots when events in the English territories in France overtook him. The death of Philip V in January 1322 was probably decisive. A completely new group of advisers came to the fore in France with the new king, Charles IV. Henry de Sully, the former king's butler, fell from favour. This was a disaster for Edward. Sully's place in the new king's favour was taken by his uncle, Charles of Valois, who was notoriously anti-English. Charles was a considerable military leader who had led the French invasion of Gascony in the 1294–8 war and who had seen the duchy pass back into English hands in 1303 with regret. He had attended his niece's coronation as Edward's queen in 1308 and been outraged at the favour shown by Edward to Gaveston. More decisive for his enmity towards Edward was probably his rivalry with Philip IV's financial adviser, Enguerran de Marigny. There were many personal incidents which bred this hatred, but one of the causes of enmity was that Marigny favoured friendship with England. Charles brought about Marigny's fall and execution in 1315 and Edward's intervention could not save him. When Roger Mortimer of Wigmore escaped from the Tower in August 1323 and fled to France, Edward blamed Charles of Valois for complicity in the plot. About this time, too, Edward's proposals for a marriage between young Prince Edward and one of Charles IV's daughters finally collapsed.
